Nonrefillable bottle

Bottle closures for non-refillable bottles, with a ball, and a stopper, consisting of one piece which is inserted into the bottle neck, but can be removed, are known. It is also known in 5 connection with these closures that the bottle neck is only formed with the upper usual opening and is provided in its interior with a ringshaped groove for retaining the stopper.

It is further known to provide piston-like stopper bodies in the form of closure parts, with ring-groove and retaining-ring, a complete closing of the bottle being, however, intended and effected, and the stopper must be entirely removed if liquid is to be poured out of the bottle.

According to the present invention a ball and a piston like stopper in the form of a closure part, with ring-groove and retaining-ring provided therein is arranged in a bottle in such a manner that the stopper remain also in position during the utilization of the bottle, and the bottle neck is provided in its interior with guides but interrupted by grooves, so deeply shaped, that the pressed-in retaining-ring permits of hollow spaces for the pouring out of the liquid.

Therefore the bottle neck is shaped in its middle part, where the Stoppers are arranged, in such a manner that channels,-in any desired number and shape,-are arranged in the bottleneck in a direction parallel to the axis thereof; the part to be inserted is shaped in the way of a piston with a ring-groove for reception of a resilient retaining ring which maintains the stopper in its position in the bottle-neck, after the whole closure arrangement has been pressed in the neck of the bottle.

The accompanying drawing shows a constructional form of the present invention by way of example.

Fig. 1 is a section through the neck of the bottle, showing at 1 the ball, at 2 the inserted stopper, at 3 the groove-shaped enlargements parallel to the axis of the bottle-neck, and at 6 the guides.

Fig. 2 is a section on line 2-2 of Fig. 1, showing the stopper at 2, the constructional form of the grooves at 3, by way of example, and the guides at 6.

Fig.'3 represents the stopper alone. In the ring groove 4, provided in its middle, a divided retaining ring 5 is inserted.

In order to make it impossible that the retaining ring 5 on the pressing-in of the stopper 2 in the middle part of the bottle-neck completely iills up these grooves,lthe groove-shaped 55 vdeepening must be of such a diameter that the diameter of the bottle neck is greater in its groove-shaped deepening, than the diameter of the ring 5 in unpressed state, or, as shown in Fig. 2, the radius of the hollow of the depression must be smaller than the radius of the stopper 2 or the ring 5.

In both cases a sufficiently large space is reliably attained between the stopper part 2 and its retaining ring 5 on the one hand, and the Walls of the grooves 3 in order to permit of the 65 outiiow of the liquid along the stopper part 2 through the grooves 3, if the ball 1 is lifted off from its position in the bottle-neck. Thus the liquid does not flow through the stopper part, but through the liquid-channel 3 in the bottle- 70 neck.

Owing to the shape of the stopper part no handling-surface is given for removing the same out of the bottle; therefore any adulteration and abuse is prevented. It will be seen from the external shape of the bottle neck that the bottle comprises a safety closure; thus the public will already have the impression of a safety-bottle by the outside of the same.

It is not necessary to use closure-parts made of metal, in connection with bottles made of glass or ceramic materials, as such metal parts (in bottles with opaque neck the part 2 can be of metal) will often cause undesired changes in the flavour of the contents of the bottle. All closureparts may consist of the same material, as the bottle is made of, with the exception of the retaining ring 5. The bottle cannot be employed again.

What I claim is:

A non-refillable bottle including a body having a neck and a valve seat formed at the inner end of the neck, a ball valve associated with the seat, the outer part of the neck having an unchanged internal diameter while the portion adjacent the seat is pressed outwardly to provide vertically extending grooves, the remaining portions with unchanged diameter positioned between the grooves forming guides for the ball valve, a retaining member engaged with the guides and provided with a groove, a resilient retaining ring seated in the groove, the said retaining member corresponding at its part accessible from above to the inner diameter of the bottle neck, while the resilient retaining ring inserted with the retaining member in the guides partially presses into the vertical grooves of the neck portion and the ball valve being arranged below the retaining member and independently thereof.
